companying drawing, forming a part of this specification.

My invention relates to car door construction and more specifically to a construction for use in refrigerator cars.

Among the objects of my invention is'to provide a circular door which eliminates the eight corner joints of the construction now in use, and an improved construction which will be air tight and which will not easily get out of order.

In the drawings in which I have shown one embodiment of my invention Figure 1 is a side elevation of part of the car showing the door in closed position;.

Fig. 2 is a side elevation-similar to Fig. 1, but showing the door open;

Fig. 3 is a vertical section substantially on the line 3-3 of Fig. 1 showing the door in full lines within the door; frame, and in dotted lines withdrawn from the door frame;

Fig. 4'is a section on the line 44 of Fig. 1; and

I 10, the upper side frame member 13, the

ceiling 14 supported from the side frame 13 and the siding 15 extending between and secured to the side frames 12 and 13.

The siding 15 is cut away to provide acircular. doorway 16 adjacent which is secured the circular door frame 17. This door frame. 17 comprises an arcuate member 17* the ends of which are secured to the floor 11 of the car and intermediate points of which are secured to diagonal braces or supports 17", which, in turn, are secured to the uprights 17 and to the frame members 12 and 13. The arcuate member 17 is provided with an annular groove 18 for' cooperating with an .arcuate sealing member carried by the circular door 19.

Fig. 5 is a section on the line 5-5 of The door 19 is mounted on a swinging sup port 20 having at its lower end an off-set bracket or arm 21 pivotally mounted in a carriage 22 movable along a track 23 5e cured adjacent the side frame 12.

The upper end of the swinging support 20is provided with an off-set guide roller 25 operating within a guide channel 26, mounted adjacent the upper side frame 13.

For effecting an air tight joint between the door 19 and the door frame 17, a mechanism, indicated in general at 27, is provided, which mechanism comprises an annular sealing strip 28 located in a groove 29 in the periphery of the door 19, a plurality of bars 30, each rigidly secured to the strip 28 and located and guided in radial passages 31 adjacent to the periphery of the door, a plurality of links 32, one pivotally connected to each of the bars 30, a rotatable disk 33 to which all of the links 32- are pivotally connected, a shaft 34 to which the disk 33 is secured, a'bearing plate 35 secured to the door 19 in which the shaft 34 is rotatably mounted and an operating lever 36 secured to the shaft 34 for rotating the latter.

A cork or rubber lining 37 may be provided for the sealing strip 28 and a canvas strip 38 may be loosely secured across the groove 29 to assist in holding the strip 28 in its proper position and to insure an air tight joint at all points between the door and the door frame.

For holding the lever 36 in proper position to effect an air tight joint between the door and the door frame, a quadrant 39 is provided which is secured to the door 19 and the lever 36 is provided with a pin 40 which is slidably and rotatably mounted in the lugs 41 on the lever to be moved into and out of openings in the quadrant 39.

The pin 40 is provided with an arm 42 which, when the pin enters one of the openings in the quadrant 39, can be swung over.

operating the swinging support.

As shown in Fig. 1, when the door is in position within the frame and the' lever 36 is 'moved over 'to the dotted line position andframe, the upper end of the lever will be 'm a position to preventoutward movement of the semi-circular portion 47 so thatthe opera iqn of effecting a tight joint between the door and frame will also lock the swinging member and 'prevent the door from being moved outwardly.

ner, by means of screws I enter 'sld 'ngs or casings 52 20 The door 19' comprises a plurality of segmentalframe members 49 having cut away overelapping portions 50 F ig. 4) which are secured .to each other in any suitable man- 51, inner and and 53 respec tively secured to the frame members 49, innor and outer cork layers 5st and 55 respectively located adjacent sidings 52. and 53 andpartitions 56 and57 spaced from each other and from f the cork layers 54 and 55 whereby dead-air spaces 58, 59 and 60 are 7 provided as shown in F at.

Two semi-circular flange members 61 and ,62 are secured to the outer face of the door to limit the distance to which the door entersl the frameand also to aid in efiecting a tight j oint;

iAny suitable fastening means such as screws 63 are provided for securing the 61 and 62 on the door. The track 23 is provided with upturned ends 61 to limit the movement of the carriage 22 and is supported in position on the 7 frajmeby means of brackets or hangers 65.

The guide channel 26is-supported in position on theside frame 13' by means of hangers 6 6.

7 7 The' operationfof my improved device is as Iollows: Assuming that the car door is :in the open'fposition shown in Fig. 2 and it isfdesired to close the door, it ismoved over to the left until the carriage is stopped 'a gainst the left hand upturned end 6 1'on V "the track 23,,in which position the door will 7 be opposite the opening 16 in the side of the car. The handle 18 of the swinging member is then grasped and the member 20 swung from the position shown in Fig. i 2

to the". position shown in Fig. "1;. This will -l move d radially outward to'e'nter the groove inthe doorframeg tion shown in dotted 7 position shown in full w rd mo e t f limited ,by the engagement of the flange V members 62; with; the

I Q positionshownin Fig.1 1 to the dotted causejth'e door tobe moved from the posilines in Fig. 3 to the lines in Fig. 3. The theldoor' 19Qwill be 'side' of the ear. The lever 36 is then moved from the full line line position to. cause the sealing strip 28: to be the lever 36 also locks the swinging member20 in position to prevent the door from moving-out of the frame.

After the lever 36 has been swung to the left far enough to effect a tight joint be- ,shown, to eflect a tight joint between door tween the door and the frame, the pin 10 is moved upwardly to engage one of the openings in the quadrant 39 and is then retated to bring the arm 42 above the lug 41-5 on the lever 36 and. to bring the openings in the arm 42 and the lug 15 into alinement LO permit a seal to be inserted through these openings.
